Founded in 2007, RetailMeNot.com is the largest digital coupon site in the US. They help hundreds of thousands of customers save money when shopping online. They are headquartered in Austin Texas, in the hip “Live Music Capital of the World”. Since the company went public in 2013, the company has doubled the number of employees from 250 to over 500.
In previous blogs, I have covered what is AVC, SuccessEHS and how Plixer’s Scrutinizer accepts Netflow, sFlow and IPFIX exports. This post will cover how these key products are combined by RetailMeNot in their WLAN deployments to optimize and support this fast growing company.
Recently Michael Patterson, the Founder and Product Manager at Plixer, Matthew St. Jean the Marketing Manager at Plixer and I had an opportunity to talk to Tim Tyndall, the Lead Network Engineer at RetailMeNot. Tim shared with us the highlights of the wireless LAN deployment and explained how they use Cisco Application Visibility and Control and Plixer’s Scrutinizer to stay in control of how their WLAN is being utilized.
Tim described the environment and culture that has become a huge part of the company’s success. RetailMeNot provides hip new offices for its employees with open work spaces and other awesome perks.
The Cisco powered wireless network supports this initiative. In fact, nearly all network connectivity is wireless. He said that employees are issued a laptop by the company and many carry in their own smartphones and tablets as well; Most of those devices being from Apple.
Employees can roam freely with reliable service that spans the company’s five floors. Even during large meetings where access density increases dramatically, service continues without any interruptions and the performance metrics they can obtain using NetFlow is exceptional and reinforce that the traffic is optimized.

Quick question for IT leaders -- can the switches on your network report 100% unsampled netflow? If they can’t, there may be elusive cybersecurity threats hiding within your network. Yes, inside your network.
Every week, I hear stories of intellectual property (IP) loss and personal identifying information (PII) being compromised. This is due in part to many agencies still approaching cybersecurity the way they always have -- guarding the edges to keep threats out. But that’s not enough anymore. With malware now being custom-written to bypass the perimeter, external drives plugged in, and the ever-present possibility of tricked or malicious insiders, monitoring inside the network is now one of the most effective ways to find and eliminate threats.

This introductory post explains how one of Cisco’s security research groups established a network data collection capability for large amounts of network traffic. This capability was necessary to support research into selected aspects of the Domain Name Service (DNS), but it can be adapted for other purposes.
DNS exploitation is frequently the means by which malicious actors seek to disrupt the normal operation of networks. This can include DNS Cache Poisoning, DNS Amplification Attacks and many others. A quick search at cisco.com/security yields a lot of content published, indicating both the criticality and exposures associated with DNS.
Our research required the ability to collect DNS data and extract DNS attributes for various analytical purposes. For this post, I’ll focus on collection capabilities regarding DNS data. Read More »
